Spintronics

The remarkable trend in electronics described by the Moore law is today experiencing increasing difficulties due to fundamental limitations in the current miniaturization approach. Alternative strategies need to be developed, e.g. exploiting a bottom-up molecular approach, mesoscopic devices, additional degrees of freedom or quantum physics. In this frame, spin is likely going to play a crucial role to carry classical or quantum information. Spintronics research in Lecce addresses different fields, from nanoscale devices based on magnetic molecules or nanoparticles to magnetic multilayers and more recent activities on RF systems for hybrid spintronics. Furthermore, we also investigate novel materials (such as multiferroics and functional oxides) and perform magnetic and ferroelectric characterizations. More in detail:

NanoElectronics/Spintronics

This research was the starting point for the group, thanks to the EU project SpiDME. To interconnect the individual building blocks at the nanoscale, we employ electron beam lithography (EBL), focused ion beam or a non- conventional method based on the selective wet-etching and oxidation of an AlGaAs/GaAs quantum well structure for the simultaneous fabrication of large arrays of nanodevices. Molecules or nanoparticles are typically positioned by specific immobilization procedures exploiting suitable functional end-groups. Charge and spin transport studies are carried out within superconducting magnets up to 10.5T and down to 10 mK.

Nanomagnetism

Nanomagnetism in magnetic materials and nanoparticles is investigated by vibrating sample magnetometry and a.c. susceptibility. Beyond hysteresis, both zero-field cooled and field cooled curves are typically acquired to evaluate the blocking temperature.

Magnetic Multilayers

Multilayer structures are the basis for giant or tunneling magnetoresistance devices. Our research focuses on the integration of further layers including nanoparticles, magnetic molecules, multiferroics or superconducting films. On the technological side, the target is to achieve a large magnetoresistance, which is useful for further applications such as in biosensors.

RF systems for hybrid spintronics

Recently, we started to investigate 3D microwave cavities and SAW devices for their integration in hybrid spintronic architectures where photons and phonons are coupled to the magnetic degree of freedom.

Multiferroics and Functional Oxides

Here we investigate high-k materials for gate stack technology in logic and memory devices and multiferroic materials for implementing novel operational concepts in spintronics exploting magnetoelectric coupling. Structural, morphological and dielectrical characterizations are typically carried out, while ferroelectric and multiferroic properties are investigated by means of PFM, KPFM, Dielectric and Ferroelectric (PUND) measurements.
